Abstract

Foods and beverage products are treated to hide the odor of trans-2-nonenal which normally occurs on storage, by treating the foods or beverages, prior to storage, by contacting with toasted granulated oak wood particles.

1 . A method of treating a food or beverage to hide or mediate the odor of trans-2-nonenal which comprises contacting the food or beverage with toasted granulated oak wood particles or an extract thereof.  
     
     
         2 . A method according to  claim 1 , wherein said toasted granulated oak wood particles are toasted, in air, at a temperature in the range of about 300° F. to about 400° F., prior to use.  
     
     
         3 . A method according to  claim 1 , wherein said toasted granulated oak wood particles comprise toasted white or red oak chips.  
     
     
         4 . A method according to  claim 1 , wherein said toasted granulated oak wood particles have a moisture content, prior to contacting with the malt beverage, of 1%, by weight.  
     
     
         5 . A method according to  claim 1 , wherein said food is frozen following said contacting.  
     
     
         6 . A method according to  claim 1 , wherein said beverage comprises a malt beverage, and is contacted with said toasted oak wood particles during krauesening or aging.  
     
     
         7 . A method according to  claim 6 , wherein said toasted granulated oak wood particles are added to said malt beverage in an amount of about 0.05 lbs. per 100 lbs. of malt beverage (or 0.13 lbs. per bbl. of malt beverage) to about 0.8 lbs. per 100 lbs. of malt beverage (or 2.0 lbs. per bbl. of malt beverage).  
     
     
         8 . A packaged food or beverage product containing linoleic acid susceptible to formation of trans-2-nonenal on storage, containing toasted granulated oak wood particles or an extract thereof to hide or mediate the odor of trans-2-nonenal.  
     
     
         9 . A packaged food or beverage product according to  claim 8 , wherein said toasted granulated oak wood particles comprise toasted white or red oak wood chips.  
     
     
         10 . A packaged food or beverage product according to  claim 8 , wherein said food comprises a frozen food.  
     
     
         11 . A packaged food or beverage product according to  claim 8 , wherein said beverage product comprises a malt beverage.
